Capillary ion electrophoresis (CIE) (Waters' trade name: Capillary Ion Analysis, CIA) is a capillary electrophoretic technique which is optimized for the rapid analysis of low-molecular-mass inorganic and organic ions. An electroosmotic flow modifier (OFM) was added to the chromate electrolyte and a negative power supply was used. Indirect UV detection at 254 nm was used throughout. Analysis of anions in a variety of drinking water samples was done. Anion analysis using this technique is rapid (less than 5.5 min), with little sample preparation required. Comparison of anion amounts found using CIA and conventional suppressed ion chromatography (IC) was done with good correlation between the two techniques.
毛细管离子电泳（CIE）（沃特世的商品名：毛细管离子分析，CIA）是一种毛细管电泳技术，针对低分子量无机和有机离子的快速分析进行了优化。向铬酸盐电解质中添加了电渗流改性剂（OFM），并使用了负电源。全程采用254nm间接紫外检测。对多种饮用水样品中的阴离子进行了分析。使用该技术进行阴离子分析速度很快（不到5.5分钟），几乎无需样品制备。对使用CIA和传统抑制离子色谱（IC）测得的阴离子含量进行了比较，两种技术之间具有良好的相关性。
